Establishment
Planting through canopy formationRoots, structure, organic matter
Give young Soursop a broad, aerated root zone before pushing rapid canopy growth. Use mature organic inputs in modest split applications.
Crop growing guide
Soursop
Annona muricata
A small tropical fruit tree with soft wood, irregular pollination, and a need for stable moisture as its large fruit develops.
Soursop (Annona muricata) flowers on trunks and branches but often sets unevenly because natural pollination can be limited. Open canopy management, hand pollination where practical, and balanced water and potassium support a smaller number of well-filled fruit.
For practical cultivation, Soursop needs its light, water, root-zone aeration, and nutrition managed as one system. The guidance below organizes those needs by growth stage; final field or container rates should follow the product label, plant size, local conditions, and soil or media analysis.
Ideal growing conditions
- Light
- Full sun, with temporary protection from severe afternoon heat while young.
- Climate
- Warm, humid tropical conditions with stable temperatures and shelter from strong wind.
- Water
- Deep, regular watering during establishment; even moisture during flowering and fruit fill without waterlogging.
- Soil
- Deep, organic-rich loam with strong drainage and a broad, uncompacted root zone.
- Soil pH
- 5.5–7.0
Nutrition by growth stage
Vegetative growth
Active shoot and canopy flushesBalanced nutrition, leaf area, resilient shoots
Support each Soursop flush steadily, then allow shoots to harden. Excess nitrogen can create soft growth and delay reproductive balance.
Flower initiation and bloom
Before buds form through full bloomPhosphorus, potassium, micronutrient balance
Soursop needs steady rather than abrupt nutrition as it shifts from shoots to flowers. Avoid a fresh surge of nitrogen at this stage.
Fruit set and fill
From successful set until harvestPotassium, water stability, fruit retention
Maintain even root moisture and potassium availability while Soursop carries fruit. Large moisture or salt swings increase stress and fruit loss.
Post-harvest recovery
Immediately after harvest and pruningCanopy renewal, roots, stored reserves
Return organic matter and balanced nutrition after harvest so Soursop can rebuild leaves, roots, and reserves for the next cycle.

Match each product to the crop stage and root zone. Final rates should follow the product label, soil condition, and local agronomic advice.
Durian Special Mix
Special organic blend formulated for fruit plant growth and crop quality.
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Fruit set and fill · Post-harvest recovery
Durian Special Mix organic nutrition can support Soursop when its use follows crop stage, soil condition, and the product label.
Best timing
Introduce during active growth and the higher-demand stages listed above; avoid a large corrective dose close to harvest or dormancy.
How to apply for this crop
Apply to moist soil around the active Soursop root zone, keep material away from stems or crowns, water in, and adjust the amount to plant size and field or container conditions.
General product guidance
Apply around the active root zone or mix into the planting media according to the package label, then water lightly. Adjust the amount to plant size, soil condition, and crop stage.
NPK 5-5-5
Alitura's Reserve
Most Balanced NPK 5-5-5 Organic Nutritional Fertilizer
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Establishment · Vegetative growth
balanced soil-building organic nutrition provides a defensible foundation for Soursop without replacing soil or leaf analysis.
Best timing
Use during soil preparation, establishment, or recovery, then reassess before the next growth stage.
How to apply for this crop
Spread evenly through the cultivated root zone or media, mix lightly where appropriate, and never pile fertilizer against Soursop.
General product guidance
Use Alitura's Reserve as a base feed at planting and as a top-up through the growing season. As a general guide, work a small handful into the soil around each plant or mix it into potting media before planting, then reapply every 4 to 6 weeks during active growth. For garden beds, broadcast evenly over the soil surface and lightly incorporate, then water in well. Powder works best mixed into soil or media. Always water after applying and adjust the amount to plant size and soil condition.
Mistakes to avoid
- Piling fertilizer against the trunk instead of distributing it through the active root zone.
- Pushing nitrogen during flowering and creating leaf growth that competes with fruit set.
- Ignoring post-harvest recovery and expecting the next crop without rebuilding reserves.
- Support or thin heavy fruit where soft branches cannot safely carry the load.
